Abstract Objective: To compare the application value of high-flexion prosthesis and rotating platform prosthesis in total knee arthroplasty (TKA). Methods: Patients with advanced knee joint pathological changes who underwent TKA in the hospital from January 2016 to May 2018 were enrolled in the study, including 50 patients treated with high-flexion prosthesis (group A) and 50 patients treated with rotating platform prosthesis (group B). The general surgical conditions (surgical time, intraoperative blood loss, loose rate of lateral joint capsule soft tissues, postoperative blood transfusion volume), clinical indicators [knee clinical score (KCS), knee function score (KFS), patellofemoral Feller score, pain visual analogue score (VAS), range of motion (ROM) of knee joint], imaging indexes (femoral angle, tibial angle, posterior slope, femoral flexion angle, Insall-Salvati value) and postoperative SF-36 quality of life scores were compared between the two groups. The incidence of complications was statistically analyzed. Results: There were no significant differences in the general surgical conditions, imaging parameters or incidence of complications between the two groups (P>0.05). KCS, KFS and Feller scores, knee ROM and SF-36 scores of both groups were significantly increased after surgery (P<0.05), while VAS scores were significantly decreased after surgery (P<0.05), There's no significant difference between the two groups (P>0.05). Conclusion: In TKA, the short-term efficacy of high-flexion prosthesis is similar to that of rotary platform prosthesis, but the clinical advantages of the latter need to be explored in a long-term follow-up.
